[1.6.1pre] no data of type text received through proxy

[tekknokrat]

We want to collect the statistic of network routes from our hosts.
so I created a new item check routes of type text which works when using zabbix_check and on non-proxied hosts.

Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
*****      0.0.0.0         255.255.255.0   U     0      0        0 eth0
0.0.0.0         *****    0.0.0.0         UG    100    0        0 eth0

When using this for hosts behind proxy the result is exactly nothing returned:

Timestamp 	Value
2008.Oct.17 17:03:10

Currently i have switched to md5sum of the route cmd and Result-Type Character in item. This seems to work but is only a workaround because admin should see the routes in webinterface.

we use sqlite for proxy and postgres for server.
